[0004]

A method according to the above-mentioned object.
The stereoscopic image reproducing device described is a pinhole panel in which a large number of pinholes opened by a specific signal are formed at a small interval, and the pinhole panel is arranged at the back of the pinhole panel, and from the individual positions corresponding to the pinholes. A three-dimensional image reproducing device comprising a small image when an image-captured object is viewed and an image reproducing panel reproduced at the same time as the opening signal of the pinhole, wherein the specific signal is used as a scan signal. The scan signal skips a predetermined number of pinholes in the horizontal direction and the vertical direction, and further, the aperture scanning of the pinholes that are successively performed is performed by designating one of the skipped pinholes. It is configured to be a sequential scan signal. The stereoscopic image reproducing device according to claim 2, which is in line with the above object, is provided with a pinhole panel in which a large number of pinholes opened by a specific signal are formed at small intervals, and is arranged on the back of the pinhole panel.
A stereoscopic image reproducing device comprising: an image reproducing panel for reproducing a small image when the object to be imaged is viewed from each position corresponding to the pinhole, simultaneously with an opening signal of the pinhole, The specific signal is a pinhole opening signal that skips a predetermined number of pinholes in the horizontal direction and the vertical direction and opens these at the same time, and the pinhole opening signal that opens at the same time is in the skipped pinhole region. It is configured to be sequentially scanned by.

[0005]

In the three-dimensional image reproducing apparatus according to the first or second aspect of the present invention, the image reproducing panel has a small image corresponding to a large number of pinholes when the image pickup object is viewed from each position. Since it is reproduced with the signal, when one sees the small image through the pinhole panel, one point (that is, one eye) can see one point of the small image through one pinhole. By looking through multiple pinholes, you can see one large image composed of each point of the small image. Therefore, when viewed from both eyes, the viewpoint of the image seen from the pinhole is different,
By inputting the image of the imaged object corresponding to each pinhole in advance to the image reproduction panel,
As a result, a stereoscopic composite image with a sense of perspective can be seen.
And in the stereoscopic image reproducing device according to claim 1,
The pinholes are skipped and sequentially scanned, and an aperture scan is performed while skipping a predetermined number of pinholes in the horizontal direction and the vertical direction, and the next aperture scan specifies one of the skipped pinholes. Since the aperture scan is performed, the serial signal can be used for controlling the pinhole panel, which can simplify the circuit. The small images displayed in correspondence with the respective pinholes need to be performed at high speed because the signals are sequential signals, but the signal transmission system can be simplified. In the stereoscopic image reproducing apparatus according to claim 2, since the pinholes are simultaneously opened in parallel in the horizontal and vertical directions at predetermined intervals and scanning is performed in parallel within the pinhole intervals opened in parallel, adjacent pinholes are adjacent. It is possible to obtain a small image larger than the area divided by, and thus a sharper stereoscopic image can be obtained. Then, the small images displayed on the image reproduction panel are displayed corresponding to the pinholes opened in parallel, so that the configuration of the image reproduction device is simplified.

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is a perspective view showing a schematic configuration of a stereoscopic image reproducing apparatus according to a first embodiment of the present invention, FIG. 2 is a side view of the stereoscopic image input apparatus, and FIG. 3 is an explanatory view of the stereoscopic image input apparatus. ,
FIG. 4 is a perspective view for explaining the operation of the stereoscopic image reproducing device.

As shown in FIG. 1, a stereoscopic image reproducing apparatus 10 according to an embodiment of the present invention includes a pinhole panel 12 having a large number of pinholes 11 formed therein, and the pinhole panel 1
The image reproduction panel 13 and the reproduction control device 14 are arranged at the rear of the image reproduction panel 13. These will be described in detail below.

The pinhole panel 12 comprises a liquid crystal panel, and according to the size of the pinhole panel 12,
Actually, 10,000 to 500,000 pinholes 11 are formed, but in order to clarify the operation of the pinholes, FIG. 1 (similarly to FIG. 3 and FIG. 4) is expressed extremely coarsely. The vertical and horizontal lines are divided into grids for easy understanding. The image reproduction panel 13 is composed of a liquid crystal display (or a cathode ray tube) and displays a pinhole image corresponding to the pinhole 11 on each image reproduction section in accordance with an image signal sent from the reproduction control device 14. It has become.

The image input to the three-dimensional image reproducing device 10 is captured by the three-dimensional image input device 15 as shown in FIG. The stereoscopic image input device 15 is
As shown in FIG. 2, it comprises a front pinhole panel 16 and an image pickup device 19 such as a CCD for converting a small image picked up by the pinhole panel 16 into an electric signal. Since the small images of the image pickup device 19 are displayed upside down, the respective small images are electrically inverted into an upright image and captured as an electric signal. In addition, it is preferable to provide a hood on the front side of the stereoscopic image input device 15 as shown by a two-dot chain line in FIG.
This makes it possible to prevent the adjacent small images formed by the individual pinholes from overlapping. Instead of the hood, the length of the pinhole with respect to the diameter may be set slightly longer to determine the light receiving region.

The pinhole panel 16 is composed of, for example, a transmissive liquid crystal panel, and pinholes are opened by horizontal and vertical scan signals of a specific frequency, and this image is formed on the image pickup element 19. ing. Further, the image pickup device 19 is scanned at a high speed by the pinhole opening scan signal of the pinhole panel 16 so as to input the image to be projected. Regarding a method of scanning a pinhole (hereinafter, simply referred to as a pinhole) formed in the pinhole panel 16,
Explaining with reference to FIG. 3, first, the pinhole panel 16 is divided into small blocks indicated by thick lines, and the pinholes P ₁ , P ₂ , P ₃ , ... P of the respective small blocks are divided.
An image a ₁ , which is displayed by opening _n ...
a _2, a _3, by forming an · · · a _n · · to the image sensor 19, converts it into an electric signal. However, the size of the small blocks in this case is determined so that pinhole images (small images) during scanning between the small blocks do not overlap. Then, the pinholes P ₁ , P ₂ , P ₃ , ... P _n ...
After closing the next pinhole Q ₁ in the same small block,
_{Q 2, Q 3, ··· Q} n ·· open at the same time, image b ₁ to be displayed by _{this, b 2, b 3, ···} b n ··
Is also converted into an electric signal by the image pickup device 19. Then, the process moves to the next pinhole and the same process is performed.
All the pinholes of each small section surrounded by the rectangle 20 are scanned to capture a predetermined pinhole image. The scan control of the pinhole panel 16 and the image pickup device 19 is performed by the image pickup control device 21, and the scan signal and the image signal are processed by the image pickup control device 21 and then input to the reproduction control device 14.

The scan signal and the image signal input to the reproduction control device 14 are subjected to predetermined signal processing to open the pinholes in the same order as shown in FIG. A small image corresponding to the pinhole is reproduced on the image reproduction panel 13. This will be described with reference to FIG. 4. The pinhole panel 12 is divided into small blocks corresponding to the small blocks of the stereoscopic image input device 15, and the same positions of the small blocks are opened at the same time so that the small blocks are opened. The small image (pinhole image) group projected on the image reproduction panel 13 can be seen through the pinhole (A
₁ ) Then, erase the small image group A ₁ and the small image group B ₁ , and simultaneously open the pinholes next to each small block,
The small image group corresponding to the pinhole is made visible (A ₂ ), and these are repeated to sequentially scan the pinholes up to A ₁₆ , and the small image groups B _{1 to} B ₁₆ corresponding to the pinhole are sequentially scanned. When the set is viewed, the stereoscopic image displayed by the stereoscopic image input device 15 as a whole can be viewed by the stereoscopic image reproducing device 10, and when the stereoscopic image reproducing device 10 is viewed, the position of the viewpoint is changed. However, the image looks three-dimensional. Where, for example,
The whole of A _{1 to} A ₁₆ and B _{1 to} B ₁₆ is called a one-dimensional frame.

In this embodiment, the pinhole panel 12 is divided into small blocks, and the image is viewed while simultaneously scanning the pinholes of the small blocks, so there is little flicker when viewing the image. The screen is easy to see. Further, although the aperture scan control of the pinhole becomes complicated, it has an advantage that the image processing becomes easy. In this embodiment, 16 pinholes are formed in the small block for ease of explanation, but the present invention is applicable regardless of whether the number is larger or smaller than this. Further, the number of the small blocks is larger, the clearer the stereoscopic image can be seen, but the field of view becomes narrow,
On the contrary, the viewing angle becomes wide. In addition, if a circuit is incorporated in the pinhole panel so that a pinhole at the same position in a small section is opened at the same time by one scan signal, the scan signal is reduced, and the circuit configuration becomes extremely simple.

Next, with reference to FIG. 4, a description will be given of a reproduction processing method for the stereoscopic image reproducing apparatus according to the second embodiment of the present invention. First, an image input method will be described and shown in FIG. In the stereoscopic image input device 15, the pinholes (P ₁ , P ₂ , P ₃ , ... P _n ···) of each small block of the pinhole panel 16 are sequentially scanned, and after this scanning is completed, the adjacent The pinholes (Q ₁ , Q ₂ , Q ₃ , ... Q _n ···) are sequentially scanned, and the next adjacent pinhole is further scanned, and each pinhole image is converted into an electric signal by the image pickup device 19. Change, thereby producing a scan signal and a stereoscopic image signal.

Next, the stereoscopic image reproducing apparatus includes a pinhole panel having a small block corresponding to the small block and an image reproducing panel arranged on the back of the pinhole panel.
When the image displayed on the image reproduction panel is viewed through the pinhole panel in which the pinhole is scanned, a stereoscopic image can be seen. In this embodiment, it is easy to scan the pinhole panel, but the image corresponding to each pinhole needs to be reproduced while the image corresponding to each pinhole is scanned at a high speed based on the scan of the pinhole. A display having properties is required. Therefore,
It is also possible to use a flat-screen television using many micro vacuum tubes.

In the above embodiment, the image was black and white, but it is also possible to separate the three-dimensional image input device into three primary colors and reproduce it in color. In the above embodiments, the stereoscopic image input device and the stereoscopic image reproduction device are connected by wire, but the signal of the stereoscopic image input device is sent on a radio wave to a distance, demodulated to reproduce the stereoscopic image. It is possible to input the signal to the device, or it is also possible to record the signal in another video recorder or the like and reproduce it by the stereoscopic image reproducing device. It is also possible to input a composite image by a computer to an input signal of the stereoscopic image reproducing device so that the composite image can be viewed stereoscopically.

[0016]

As is apparent from the above description, the stereoscopic image reproducing device according to the first and second aspects has a large number of pinholes arranged at a small interval, and the back of the pinhole corresponds to the pinholes. Since an image reproduction panel for reproducing a small image is provided and the pinhole openings are shifted to perform high-speed scanning to increase the number of pinholes, a precise stereoscopic image with less flicker can be viewed. This stereoscopic image allows multiple people to observe the stereoscopic image at the same time without wearing special equipment such as glasses, and it is also possible to observe the stereoscopic image by changing the viewing angle. The eyes can be focused on and natural vision can be achieved.
